lailaayelet Sorry - I have no idea what you mean, but calling someone of whom you know nothing, "unnatural" reflects you, not your victims.
Of course breeding is natural, indeed biologically necessary, not for any individual organism once it has grown, but for its species at large. We humans are no different, we have our own mating instincts as any animal does; but we have
more than just instinct. We have powerful intellects and choices too.
Many people stay childless either by choice (as their right) or by infertility (possibly treatable, if they so choose, as is also their right).
Others still, never have the opportunity to try. They genuinely cannot attract a mate, or they might do but are too poor to support a family properly so choose not to breed.
A few of course abjure relationships entirely, such as those who become momks or nuns. That is their choice although certainly not one I understand or would take!
There are also, anecdotally, couples who choose not to have children because they fear for the future of the world. If so, again, that is their choice.
Are any of those people "un-natural? Of course not!
My critiscism was not of people being single or childless although I am puzzled why you seem to condemn them.
Instead I questioned the call for "true Catholics" to exclude bachelors, spinsters and widows/ers - while accepting preaching from men who have chosen to be celibate bachelors!
If it
does mean that, such exclusion is mere prejudice: ignorant, cruel, childish and cowardly.
